Hi, I have had severe constipation for the last six months followed by severe diarrhea. I will be constipated for three days and then have diarrhea all day the next day and when I get the diarrhea, I have severe lower abdomin pains on my left side. I know this may not help, but I also, have issues with frequent urination. I am so frustrated!! I have been to the doctor and they have no idea what is wrong with me and think that I am just paranoid. Trust me I am not paranoid. I just don't know what else to do!! Please help me, do you have any ideas of what this could be?
